Title: Hydraulic brake controller for vehicle
Inventor: ARIKAWA TETSUO
IPC: B60T8/48
Filed: 1988-11-04
Abstract: PURPOSE:To secure such a vehicle hydraulic brake controller that has both functions of braking slip control and driving slip control, besides compact in size and lighter in weight, by installing a valve gears which is freely interconnected to both directions of the discharge side of a hydraulic pump and the side of a master cylinder usually, but in a specified case, interrupting both sides. CONSTITUTION:At time of braking, a selector valve 7 is situated in an A position by a signal out of a control unit 12, whereby a wheel 9 is braked. When this wheel 9 is made so as to exceed the specified deceelation due to a rise in brake fluid pressure, the selector valve 7 takes a B position, and pipelines 6 and 8 is made into a state of being interrupted whereby braking force to the wheel 9 is kept constant. When the wheel 9 is made so as to exceed the specified slip factor, the selector valve 7 takes a C position so that the brake of the wheel 9 is reduced. With this constitution, driving slip control also is made so as to be done by only adding a valve gear to a braking slip device.

Filed: 1993-11-09
Abstract: PURPOSE:To eliminate lower degree harmonics by a method wherein the resul tant value of the AC current of a plurality of converters is so controlled as to have a sine wave form. CONSTITUTION:The output current command value vector of a converter is given by an AC current command value generating circuit 45 as the components on U-V-W coordinates. The components on the U-V-W coordinates are converted into components on A-B coordinates by the arithmetic operation of a 3-phase/2- phase converter 46 composed of an adder and a multiplier. The phase angle of the command value vector is detected by the arithmetic operation of phase detecting circuit 47 in accordance with a sine function to generate an command vector signal. The components on the A-B coordinates are converted into components on AX-BX coordinates whose phase is 30 deg. ahead of the phase of the A-B coordinates by the arithmetic operation of a coordinate converter 48 composed of a sine function. The components on the AX-BX coordinates are converted into components on coordinates which are turned by 60 deg.. The obtained components are converted into components om coordinates which are turned by 60 deg. with the AX-BX coordinates as a reference by the arithmetic operation of 2-phase/3-phase converter 50.

Title: Observation of image formation condition in semiconductor image position detecting element
Inventor: IDESAWA MASANORI
IPC: G02B7/32
Filed: 1989-10-26
Abstract: PURPOSE:To facilitate adjustment to optimum image forming condition by scanning a spot image traversing a boundary between a dead part provided at a detecting section of an element and a photosensitive section to observe a state of change in an output signal value generated between the dead part and the photosensitive part. CONSTITUTION:A boundary is assumed which has sensitivity to light on one side and no sensitivity on the other side when light forms an image at an end of a semiconductor image position detecting element (PSD). In a brightness distribution of a spot image, J' is a brightness distribution with the focus off and J a brightness distribution under optimum conditions. A density distribution of current flowing into a resistance layer also shows a distribution similar to this. When a spot image having such an brightness distribution traverses a dead part like an end of the PSD, a sharpness of the spot image, namely, propriety in adjustment of focus is reflected as change in the photocurrent to be detected at an output terminal. Therefore, a focusing mechanism is adjusted so that a degree of the change in the photocurrent becomes the steepest thereby achieving the best image forming condition.

Abstract: PURPOSE:To eliminate heat dissipating loss and pressure loss upon both of heat collecting operation and waste heat retrieving operation by a constitution wherein a heat pump cycle is constituted of a collector or a waste heat retrieving heat exchanger, operating as an evaporator with respect to a compressor, and a hot-water heat exchanger, operating as a condenser with respect to the compressor. CONSTITUTION:Condensed refrigerant liquid from the hot-water heat exchanger 3 flows into the collector 8 from an expansion valve 9 through first solenoid valve 7 and second solenoid valve, both of which are being opened. Then, the refrigerant liquid is evaporated by collecting solar heat and atmospheric heat, thereafter, flows out of the collector 8 and is induced into the compressor 1 from first nonreturn valve 11 through an accumulator 3. According to above-described heat pump cycle, hot-water is made by collecting solar heat, however, the refrigerant will never flow into the waste heat retrieving heat exchanger 4 by the effects of third solenoid valve 12 and second nonreturn valve 14, therefore, heat dissipation or pressure loss will never be generated in the waste heat retrieving heat exchanger 4 whereby efficient solar heat collecting operation may be effected.
